Passage 13
Researchers
have
established
that
when
people
are
mentally
engaged,
biochemical
changes
occur
in
the
brain
that
allow
it to
act
more
effectively
in
cognitively
areas
such as attention and
memory. This is true regardless of age.
People will be alert and receptive if
they are faced with information that gets them to
think about things they are interested
in. And someone with a history of doing more
rather than less will go into old age
more cognitively sound than someone who has
not had an active mind.
Many
experts are so convinced of the benefits of
challenging the brain that they are
putting the theory to work in their own
lives.
“
The idea is not necessarily to learn to
memorize enormous amounts
of information,
”
says James Fozard, associate director
of the
National Institute on Aging.
“
Most of us don
’
t need that kind of skill. Such
specific
training
is
of
less
interest
than
being
able
to
maintainmental
alertness.
”
Fozard and others say
they challenge their brains work.
Gene
Cohen, acting director of the same institute,
suggests that people in their old age
should
engage
in
mental
and
physical
activities
individually
as
well
as
in
groups.
Cohen says that we are
frequently advised to
keep physically active as
we age, but
older people need to keep mentally
active as well. Those who do are more likely to
maintain
their
intellectual
abilities
and
to
be
generally
happier
and
better
adjusted.
“
The point is,
you need to do both.
”
Cohen says,
“
Intellectual activity actually
influences brain-cell
health and size.
”
61.
People who are cognitively healthy are
those________
A) who can remember large
amounts of information
B) who are
highly intelligent C) whose minds are alert and
receptive
D) who are good at
recognizing different sounds
62.
According
to
Fozard
’
s
argument,
people
can
make
their
brains
work
more
efficiently by___
A)
constantly doing memory work B) taking part in
various mental activities
C) going
through specific training D) making frequent
adjustments
63. The findings of James
and other scientists in their work_______
A) remain a theory to be further proved
B) have been challenged by many
other experts
C) have been generally
accepted
D) are practiced by the
researchers themselves
64. Older people
are generally advised to _______
A)
keep fit by going in for physical activities
B) keep mentally active by challenging
their brains
C) maintain mental
alertness through specific training
D)
maintain a balance between individual and group
activities
65. What is the passage
mainly about?
A) How biochemical
changes occur in the human brain
免费？宅在家学英语？怎么报名？
B) Why people should keep active not
only physically but also mentally
C)
How intellectual activities influence brain-cell
health
D) Why people should receive
special mental training as they age.
Passage 13
研究学者已经得出观点，
当人们精神上投入时，
大脑中也会发生生 人变化，
使它
在注意力和记忆力这样的认知领域动作效率更高。
这一事实与年龄无关。
（６１）
当人们面对可以联想到感兴趣事物
的信息时，
便会警觉起来，
接受能力强。
而习
惯于多进行这种活动的人比那些从来没有积极主动思考的人在步入老年时明显
更加健
康。
许多专家确信，
向大脑提出挑战是极有好处的，< /p>
因此他们将这一理论应于自己身
上。国立老化研究所的副主任（６２）
James
Fozard
说：
“关键不是非得学会记
忆大量的信息。
我们大多数人并不需要那种技巧。
这种特 别的培训没有保持精神
集中的能力更加有趣。
”
（６３）
Fozard
与其他人都宣称他们用各种不同的精神技
巧
向自己的大脑提出挑战，
不仅因为他们喜欢这样，
还因为他们确信自己的活动
领域有助于大脑工作的方式。
Gene
Cohen
是同一研究所的代理主任，他建议年纪较大的人参加脑力与体力活
动时应使独自参与和集体行动兼而有之。
Cohen
说（６４）我们通 常得到的建议
时在年纪增长时要保持身体上的活动，
但老人也需要保持精 神上的活力。
这样做
的人更有可能保持其智力水平，
通常 更加愉快，
能更好地调节自己的生活。
Cohen
说，<
/p>
“关键是，你得双管齐下。智力行为的确对脑细胞的健康与大小有影响。
”
